[Outline of Information Processing Apparatus 100]

FIG. 1 schematically illustrates an example of a system configuration of an information processing apparatus 100. In the present embodiment, the information processing apparatus 100 provides information on, for example, the charge state of one or more storage batteries stored in each of one or more charging devices to a user who uses the storage battery. In the present embodiment, the information processing apparatus 100 includes, for example, an arrangement information acquisition unit 110, a user position acquisition unit 120, a charge state acquisition unit 130, and a state information generation unit 140.

In the present embodiment, the arrangement information acquisition unit 110 acquires, for example, arrangement information indicating a position where a charging device for charging one or more storage batteries is located. In the present embodiment, the user position acquisition unit 120 acquires, for example, user position information indicating the position of the user. In the present embodiment, the charge state acquisition unit 130 acquires, for example, information indicating the charge state of at least one of the one or more storage batteries at specific time. The specific time may be time when the information processing apparatus 100 is requested to provide information on the charge state of the storage battery. Examples of the charge state include SOC, a voltage, and the like.

In the present embodiment, the state information generation unit 140 generates information of at least one of the one or more storage batteries associated with, for example, (i) the charge state at the specific time, and (ii) the charge state at estimated time when the user arrives at the charging device (may also be referred to as estimated time of arrival) on the basis of (i) arrangement information acquired by the arrangement information acquisition unit 110, and (ii) user position information acquired by the user position acquisition unit 120. Generating information may be an example of acquiring information.

The charge state at the estimated time of arrival can be acquired, for example, according to the following procedure. First, the state information generation unit 140 acquires information on a charging speed of the charging device and information on a moving speed of the user. Examples of the information on the charging speed include a rated value of the charging speed, a statistic amount of the charging speed calculated from the past history, and the like. Examples of the statistic amount include mean, trimmed mean, median, and mode. The information on the charging speed of the charging device may include information on the charging speed when the charging device charges each of one or more storage batteries stored in the charging device. Examples of the information on the moving speed of the user include a moving speed determined from traffic rules, a statistic amount of the moving speed calculated from the past history.

Next, the state information generation unit 140 estimates the time when the user arrives at the charging device on the basis of the arrangement information, the user position information, and the information on the moving speed of the user. Next, the charge state of the storage battery at the estimated time of arrival is estimated on the basis of the specific time (e.g., the current time), the estimated time of arrival, and the information on the charging speed of the charging device. Specifically, a period between the specific time and the estimated time of arrival is calculated first. Next, on the basis of the period mentioned above and the charging speed of the charging device, an amount of change in the charge state in the period is calculated. The amount of change in the charge state of each storage battery during the above period may be calculated on the basis of the charging speed of each storage battery of the charging device. Next, the charge state at the estimated time of arrival is calculated on the basis of the charge state at a specific time and the amount of change in the charge state during the period mentioned above.

For example, when the deterioration state varies among a plurality of storage batteries stored in the charging device, the charging speed may vary for each storage battery. Also, in some charging devices, the charging may not start immediately after the storage battery is stored, but the storage battery may be charged according to a predetermined charge schedule or rule. Therefore, if a relatively long period of time has passed before the user actually receives the storage battery after the user checks the charge state of the storage battery in advance, the charge state of the storage battery, when received, may be different from what the user has expected. According to the present embodiment, the user can select a storage battery that the user wants to use from a plurality of storage batteries stored in the charging device by considering, for example, not only the charge state at the time when the user checks the charge state of the storage battery, but also the charge state at the time when the user is scheduled to arrive at the charging device. This largely improves convenience and satisfaction of the user.

Next, when the occurrence of the event is detected, the adjustment target extraction unit 624 extracts one or more battery stations related to the battery station in which the event has occurred from the plurality of battery stations to be managed. The adjustment target extraction unit 624 may refer to the relevance information storage unit 574 and extract one or more battery stations related to the battery station in which the event has occurred on the basis of the relevance between the battery stations.

For example, when the event detection unit 622 detects the abnormality or the stop of the battery station 210, the adjustment target extraction unit 624 extracts the battery station (e.g., one or more battery stations 212) whose relevance to the battery station 210 satisfies a predetermined condition as the battery station related to the battery station 210. The predetermined condition may be determined on the basis of at least one of (i) an item related to specifications, (ii) an item related to rent record, and (iii) an item related to the utilization rate of the battery station 210 in which the abnormality or the stop has been detected.

According to one embodiment, the condition is determined in a manner that the larger the maximum storage number and/or the charging capacity of the battery station 210, the wider the range of battery stations extracted as the battery stations related to the battery station 210. According to another embodiment, the condition is determined in a manner that the larger the predicted value of the number of rent items, which is calculated on the basis of the past rent record, during the period until the abnormality or stop is resolved, the wider the battery stations extracted as the battery stations related to the battery station 210. According to yet another embodiment, the condition is determined in a manner that the larger the target condition of the utilization rate in the period until the abnormality or the stop is resolved, the wider the range of the battery stations extracted as the battery stations related to the battery station 210.

In the present embodiment, the adjustment amount determination unit 626 determines to adjust the utilization rate of at least one of the one or more adjustment targets extracted by the adjustment target extraction unit 624. For example, the adjustment amount determination unit 626 determines the battery station to be actually subjected to adjustment of the utilization rate from the target for adjustment extracted by the adjustment target extraction unit 624 on the basis of at least one of (i) an item related to a specification, (ii) an item related to a rent record, (iii) an item related to the utilization rate, and (iv) a located position of the battery station to be adjusted.

According to one embodiment, the adjustment amount determination unit 626 determines adjustment of the utilization rate of the battery station having a large maximum storage number and/or a large charging capacity from one or more battery stations 212 extracted by the adjustment target extraction unit 624. According to another embodiment, the adjustment amount determination unit 626 determines the battery station to be actually subjected to adjustment of the utilization rate so as to decrease the geographical variation from the one or more battery stations 212 extracted by the adjustment target extraction unit 624.

Further, the adjustment amount determination unit 626 may determine the adjustment amount of the target condition of the utilization rate (which may also be referred to as the adjustment amount of the utilization rate) for the battery station determined to be subjected to adjustment of the utilization rate by the adjustment amount determination unit 626. The adjustment amount determination unit 626 may determine the adjustment amount of the target condition of the utilization rate for each of the one or more adjustment targets extracted by the adjustment target extraction unit 624.

In one embodiment, the adjustment amount determination unit 626 determines the adjustment amount of the target condition of the utilization rate on the basis of the relevance between the battery station whose utilization rate is determined to be adjusted by the adjustment amount determination unit 626 and the battery station 210. In another embodiment, the adjustment amount determination unit 626 determines the adjustment amount of the target condition of the utilization rate on the basis of at least one of (i) an item related to the specification, (ii) an item related to the rent record, and (iii) an item related to the utilization rate of the battery station 210 in which the abnormality or the stop is detected. The adjustment amount determination unit 626 may determine the adjustment amount of the target condition of the utilization rate on the basis of at least one of the specification, the rent record, and the utilization rate of the battery station 210 according to the same procedure as the extraction processing in the adjustment target extraction unit 624.

For example, the battery information acquisition unit 716 acquires information indicating the charge state at the current time or the latest measurement time. The battery information acquisition unit 716 may acquire information regarding the charging speed when the arbitrary mobile battery 22 is charged by the battery station in the past.

In the present embodiment, the station information acquisition unit 718 acquires various kinds of information regarding the battery station. The station information acquisition unit 718 may acquire arrangement information indicating the position where the station is located from the station information storage unit 576. For example, the station information acquisition unit 718 acquires the arrangement information of the battery station indicated by the station ID using, as a key, the station ID included in the reservation information acquired by the reservation information acquisition unit 714. The station information acquisition unit 718 may acquire information indicating the priority order of the one or more mobile batteries 22 stored in the battery station indicated by the station ID, using, as a key, the station ID included in the reservation information acquired by the reservation information acquisition unit 714.

In the present embodiment, the estimation unit 720 estimates the charge state of the mobile battery 22 at specific time in the future. For example, the estimation unit 720 estimates the charge state of a specific mobile battery 22 at scheduled time when the user identified by a user ID included in reservation information of the specific mobile battery 22 arrives at the battery station (which may also be referred to as estimated time of arrival) identified by the station ID included in the reservation information.

The estimation unit 720 estimates the charge state of the mobile battery 22, for example, according to the following procedure. First, the estimation unit 720 estimates the estimated time of arrival. For example, the estimation unit 720 acquires reservation information from the reservation information acquisition unit 714. The reservation information may include information indicating the position of the user at the reservation time. The reservation time may be an example of the specific time. The estimation unit 720 acquires the arrangement information of the battery station identified by the station ID included in the reservation information from the station information acquisition unit 718. The estimation unit 720 acquires information on the moving speed of the user identified by the user ID included in the reservation information from the history information acquisition unit 712. Then, the estimation unit 720 estimates the estimated time of arrival on the basis of the arrangement information of the battery station, the information indicating the position of the user at the time of reservation, and the information indicating the moving speed of the user. The estimation unit 720 may estimate the estimated time of arrival by further using traffic information, accident information, weather information, and the like. When the reservation information includes information indicating the scheduled time of receipt, the scheduled time of receipt may be used as the estimated time of arrival.

Next, the estimation unit 720 estimates the amount of change of the charge state if the mobile battery 22 is charged between the reservation time and the arrival time. Examples of the amount of change in the charge state include, for example, an increase amount of the SOC. First, the estimation unit 720 acquires information, from the history information acquisition unit 712, on the charging speed at which the battery station identified by the station ID included in the reservation information charges the mobile battery 22 identified by the battery ID included in the reservation information. The information regarding the charging speed may be the statistic amount of the charging speed. The estimation unit 720 may use the charging speed at which the battery station identified by the station ID included in the reservation information charges another mobile battery 22 as the information on the charging speed of the mobile battery 22 identified by the battery ID included in the reservation information. The estimation unit 720 estimates the amount of change of the charge state on the basis of the information related to the reservation time, the estimated time of arrival, and the charging speed.

Next, the estimation unit 720 estimates the charge state at the estimated time of arrival. The estimation unit 720 acquires, for example, information indicating the charge state of the mobile battery 22 identified by the battery ID included in the reservation information at the reservation time from the battery information acquisition unit 716. If the charge state at the reservation time is unknown, the estimation unit 720 may access the battery information storage unit 572 and acquire information indicating the charge state at the time closest to the reservation time. The estimation unit 720 estimates the charge state at the estimated time of arrival on the basis of the charge state at the reservation time and the amount of change of the charge state.

In the present embodiment, the estimation unit 720 temporarily estimates the usage situation when the user uses a specific mobile battery 22. For example, when the user uses the mobile battery 22 as the power source of the moving object, the estimation unit 720 estimates the distance that can be traveled using the mobile battery 22. The estimation unit 720 acquires information on the fuel consumption or electric fuel consumption, or the power consumption per unit time of the user from the battery information acquisition unit 716. Examples of the unit time include a time period of 1 hour, 1 day, and the like. The estimation unit 720 calculates a travelable distance on the basis of the charge state at the estimated time of arrival, the fuel consumption, the electricity consumption or the power consumption described above.

In the present embodiment, the price setting unit 730 generates information related to at least one of the usage fee, incentive, and penalty of the mobile battery 22. In one embodiment, the price setting unit 730 sets a discount fee or an incentive. For example, the price setting unit 730 acquires information regarding the priority order set for the mobile battery 22 from the station information acquisition unit 718. The estimation unit 720 sets the discount fee or the incentive when the priority order satisfies a predetermined condition. Examples of the predetermined condition include the condition of being ranked higher than a predetermined rank.

In another embodiment, the price setting unit 730 sets an extra fee or penalty. For example, the price setting unit 730 acquires information regarding the priority order set for the mobile battery 22 from the station information acquisition unit 718. The estimation unit 720 sets the extra fee or the penalty when the priority order satisfies a predetermined condition. Examples of the predetermined condition include, for example, the condition of being ranked lower than a predetermined rank. The estimation unit 720 may set the extra fee or the penalty corresponding to an additional request from the user.

In the present embodiment, the user request acquisition unit 740 acquires various requests from the user terminal 230. For example, the user request acquisition unit 740 acquires a search request for requesting a search for a battery station that meets a specific condition from the user terminal 230. The user request acquisition unit 740 acquires a reservation request for requesting reservation of any or specific mobile battery from the user terminal 230. Upon receipt of the request from the user terminal 230, the user request acquisition unit 740 starts information processing corresponding to the request.

In the present embodiment, the UI screen generation unit 750 generates a UI screen. For example, the UI screen generation unit 750 generates data for causing the user terminal 230 to generate the UI screen (which may also be referred to as UI screen data). The UI screen generation unit 750 generates, for example, data of the UI screen that provides a search request GUI in response to the receipt of the search request by the user request acquisition unit 740. The UI screen generation unit 750 may generate the UI screen data that provides a reservation request GUI in response to the receipt of the reservation request by the user request acquisition unit 740. When the UI screen data is executed on the user terminal 230, the UI screen in which, for example, (i) the charge state at specific time and (ii) the charge state at the estimated time of arrival of the user are associated for at least one of the one or more mobile batteries 22 may be output to the user. The UI screen generation unit 750 may generate the UI screen data for displaying, for example, by associating the charge state at the time when the search request or the reservation request is transmitted or received with the charge state at the estimated time of arrival of the user. The time when the search request or the reservation request is transmitted or received may be an example of the specific time. Details of the UI screen will be described later.

The UI screen generation unit 750 generates the UI screen data according to, for example, the following procedure. The UI screen generation unit 750 first acquires information on the charge state of each of the one or more mobile batteries 22 that matches the search request or the reservation request at the time when the search request or the reservation request is transmitted or received from the battery information acquisition unit 716. The UI screen generation unit 750 acquires information on the charge state of each of the one or more mobile batteries 22 at the estimated time of arrival at each of the one or more battery stations that match the search request or reservation request from the estimation unit 720. Next, the UI screen generation unit 750 generates, on the basis of the information on the charge state from the battery information acquisition unit 716 and the information on the charge state from the estimation unit 720, the UI screen data for display by associating the charge state of each of the one or more mobile batteries 22 at the time when the search request or the reservation request is transmitted or received with the charge state of each of the one or more mobile batteries 22 at the estimated time of arrival. The UI screen generation unit 750 may further generate the UI screen data to which an item related to at least one of the usage fee and the incentive is associated.
